Blastocystis hominis as a cause of chronic diarrhea in low-resource settings:A systematic review

BACKGROUND Blastocystis hominis(B.hominis),an anaerobic unicellular protist parasite,is known for its diverse clinical manifestations upon infecting the human gastrointestinal tract.Although globally distributed,it is particularly prevalent in developing nations.Examining the symptoms and treatment outcomes of B.hominis infection in low-resource settings holds immense significance,providing healthcare practi-tioners with valuable insights to enhance patient care.AIM To synthesize existing evidence on the symptomatology and treatment outcomes of B.hominis infection in low-resource settings.METHODS Following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines,a systematic review was conducted.The search spanned electronic databases including PubMed,Scopus,and Google Scholar.After a comprehensive screening process,a thorough examination of the papers,adhering to inclusion and exclusion criteria,and data extraction from eligible studies was conducted.The findings underwent summarization through simple descriptive analysis.RESULTS The search yielded 1200 papers,with 17 meeting inclusion criteria.Chronic diarrhea due to B.hominis infection was reported in only two studies,while abdominal pain,diarrhea,flatulence,constipation,and nausea/vomiting emerged as the most commonly documented symptoms.Recovery rates after one week of treatment ranged from 71.8%to 100%,and after two weeks,from 60%to 100%.CONCLUSION In low-resource settings,chronic diarrhea resulting from B.hominis infection is infrequent.Common symptoms include abdominal pain,diarrhea,flatulence,constipation,and nausea/vomiting.Post-treatment,clinical outcomes are notably favorable,supporting the recommendation for treatment.Metronidazole is advocated as the first-line agent,with consideration for switching to a second-line option in cases of treatment failure or poor response.

Continuous Wear of Hydrogel Contact Lenses for Therapeutic Use

Purpose: To investigate the efficacy and complications of continuous wear of etafilcon A for therapeutic use. Materials and Methods: The subjects were 228 eyes of 219 outpatients prescribed contact lens (CL) for one week of continuous therapeutic wear during 10 years. The reason for prescription of CLs, the primary disease, the duration of CL wear and the complications were assessed retrospectively. Results: The predominant reason for prescription of CLs was relief of pain or a foreign-body sensation (62.3%) and protection of the corneal epithelium (20.6%). The primary disease was post-penetrating keratoplasty (36.8%), followed by corneal epithelial erosion (14.5%), post-lamellar keratoplasty (14.0%) and bullous keratopathy (12.2%). The average duration of wearing single lens was 6.5 ± 3.2 days. The average duration of wearing CLs in total was 9.2 ± 10.7 months. The most frequent problem associated with continuous wear of CLs was their dropping out of CLs (12.3%). The complications associated with CLs included conjunctivitis with papillary hyperplasia, corneal erosion and superficial punctate keratitis, but corneal ulcer and corneal infiltrates were not found. Conclusion: Serious complications were not shown changing the lenses every week to keep to the prescribed time limit for continuous therapeutic wear, even if corneal epithelial barrier function is impaired.

Comparison of long-lasting therapeutic effects between succimer and penicillamine on hepatolenticular degeneration

AIM To compare the long term effect of succimer (Suc) with that of penicillamine (Pen) in treating hepatolenticular degeneration (HLD). METHODS One hundred and twenty patients with HLD were divided into 2 groups. Group A ( n =60) received Suc 750mg , po. bid. Group B ( n =60) received Pen 250mg , po. qid. The period of maintenance treatment varied from 6 months to 3 years, averaging 1 5 years. Symptoms and therapeutic effects were evaluated by modified Goldstein scale. RESULTS The total effectiveness of group A in two different periods of treatment were 80% and 85% respectively, higher than those of group B (58% and 59% respectively) ( P <0 05). Suc also had obvious curative effects for the patients who failed in the use of Pen. There were fewer side effect in group A than in group B ( P <0 05). Suc and Pen could increase urinary copper excretion effectively and continually. CONCLUSION Suc is more effective and safer than Pen. Clinically, it can replace Pen as first choice drug for long term maintenance therapy of HLD.

Therapeutic role of template-based lymphadenectomy in urothelial carcinoma of the upper urinary tract

Lymphadenectomy for urothelial carcinoma of the upper urinary tract has attracted the attention of physicians. The mapping study of lymphatic spread has shown that a relatively wide area should comprise the regional nodes for tumors of the right renal pelvis or the right upper two-thirds of the ureter. A prospective study showed that an anatomical templatebased lymphadenectomy significantly improved patient survival in tumors of the renal pelvis. This benefit was more evident for patients with p T2 stage tumors or higher. The risk of regional node recurrence is significant reduced by template-based lymphadenectomy,which is likely to be associated with improved patient survival. The removal of lymph node micrometastases is assumed to be the reason for therapeutic benefit following lymphadenectomy. The number of resected lymph nodes can be used to assess the quality of lymphadenectomy,but not to determine the extent of lymphadenectomy. The guidelines currently recommend lymphadenectomy for patients with muscle-invasive disease,even though the current recommendation grades are still low. The present limitation of lymphadenectomy is the lack of standardization of the extent of lymphadenectomy and the randomized trials. Further studies are warranted to collect the evidence to support lymphadenectomy.

Combination of "low-dose" ribavirin and interferon alfa-2a therapy followed by interferon alfa-2a monotherapy in chronic HCV-infected nonresponders and relapsers after interferon alfa-2a monotherapy

AIM To report on the efficacy, safety and tolerability of interferon alfa-2a combined with a "low dose" of ribavirin for relapsers and non responders to alpha interferon monotherapy.METHODS Thirty-four chronic hepatitis C virus-infected non-responders to interferon alfa2a monotherapy (a course of at least 3 months treatment) and 13 relapsers to interferon alfa 2a monotherapy (a dose of 3 to 6 million units three times per week for at least 20 weeks but not more than 18 months) were treated with the same dose of interferon alfa-2a used before (3 to 6 million units three times per week) and ribavirin (10 mg/ kg daily) for 6 months. In complete responders, interferon alfa-2a was administered for further 6 months at the same dose used before as monotherapy.RESULTS Seven (20.6%) of 34 non-responders stopped the combined therapy due to adverse events, including two patients with histological and clinical Child A cirrhosis. In 17/27 (63%)non-responders, the combined therapy was stopped after three months because of non-response. Ten of the 27 non-responders completed the 1;2-month treatment course. At a mean follow up of 28 months (16- 37 months)after the treatment, 4/10 (15%) previous non-responders still remained complete responders,All 13 previous relapsers completed the 12-month treatment course. At a mean follow up of 22months (9 - 36 months) after treatment, 6/13(46%) the previous relapsers were stillsustained complete responders.CONCLUSION Our treatment schedule of the combined therapy for 6 months of interferon alfa2a with a low dose of ribavirin (10 mg/kg/day)followed by 6 months of interferon alfa-2amonotherapy is able to induce a sustainedcomplete response rate in 15% of non-responders and 46% of relapsers with chronic hepatitis C virus-related liver diseases comparable to those obtained with the standarddoses of ribavirin 1000 - 1200 mg/day.Randomized prospective controlled trials using lower total amounts of ribavirin in combination with interferon should be performed.
